Abstract
The utility model relates to the field of single crystal furnaces, in particular to a seed crystal lifting and rotating mechanism of a single crystal furnace. The seed crystal lifting and rotating mechanism comprises a driving motor and a tank body driven by the driving motor, wherein the tank body comprises two rotating shafts, one shaft rotates along with the motor, a rolling wheel is fixed on the rotating shaft, a platy gear is arranged at one side of the rolling wheel, a steel wire rope is arranged on the rolling wheel, the other rotating shaft is provided with a clump weight, the clump weight is meshed with the platy gear by teeth, a connector is arranged at the lower end of the steel wire rope and connected with a counter weight, and a clamping head used for clamping seed crystals is arranged at the end of the counter weight. The seed crystal lifting and rotating mechanism has the advantages of achieving good lifting stability by a simple structure, reducing the height of the equipment to 90 percent, achieving an ideal using effect, greatly improving the qualification rate, and having simple structure, low manufacturing and using costs and good maintaining and using effects.
Description
Technical field
The utility model relates to the single crystal furnace device field, and especially a kind of seed crystal of single crystal growing furnace lifts rotating mechanism.
Background technology
Traditional monocrystaline silicon stove is mainly used in the production silicon semiconductor material, and monocrystaline silicon stove comprises silicon semiconductor material growth synthetic master furnace chamber, is positioned at the silicon seed lifting structure and the automatically controlled automatic yarn system of main furnace chamber upper end.The structure that promotes the silicon seed of traditional monocrystaline silicon stove adopts hard axle rotation and lifts, thereby makes central shaft longer, causes device height more higher, and the rotary pulling poor stability, causes the product percentage of A-class goods low, use cost height, maintenance trouble.
Summary of the invention
The utility model provides a kind of seed crystal of single crystal growing furnace to lift rotating mechanism at the shortcoming that exists in the above-mentioned technology, and it has and lifts advantage stably, has overcome the weak point that exists in the above-mentioned technology.
The technical scheme that realizes the utility model purpose is as follows:
The seed crystal of single crystal growing furnace lifts rotating mechanism, it comprises drive-motor and the casing that is driven by drive-motor, comprises two rotating shafts in the casing, and a rotating shaft is rotated with motor, be fixed with rolling wheel in this rotating shaft, the rolling wheel side is provided with the sheet gear, and rolling wheel is provided with wireline, and another rotating shaft is provided with balancing weight, this balancing weight and sheet gear are connected with a joggle by tooth, the wireline lower end is provided with linker, and linker is connected with weight, and the weight end is provided with the dop that is used for the clamping seed crystal.
Described casing is provided with damping cover line outlet, and wireline passes with linker from this damping cover line outlet and is connected.
Be provided with small machine in the described linker, this small machine is connected with weight by shaft coupling.
Adopted such scheme, wireline has replaced hard axle to greatly reduce the height of equipment, adopts the cooperation of balancing weight, on one side make rolling wheel can not stress when the coil silk, is that balancing weight plays balance, stable effect.
Benefit of the present utility model is to realize the rotary pulling good stability with simple structure, reduces device height and reaches 90%, reaches the ideal result of use, increased substantially the percentage of A-class goods of product, and simple in structure, the making use cost is low, maintenance and easy to use effective.
